What are the stages of the breakup of pangaea?
The breakup of Pangaea occurred in several stages over millions of years. It started with the rifting of Pangaea into two supercontinents, Laurasia and Gondwana, during the Triassic period. This was followed by further breakup into the continents we know today during the Jurassic and Cretaceous periods.
The continental shelf continental slope and continental rise combine to form the?
The continental shelf is basically an extension of a continent into an ocean. It is underwater during interglacial periods (such as today) but dry during glacial periods. The continental slope is the sloping area between the continental shelf and the continental rise (where the continental plate meets the oceanic plate). The continental shelf and the continental slope together are called the continental margin. The continental rise is located at the bottom of the continental slope and is formed by the accumulation of sediment from the continent. Past the continental rise lies the abyssal plain which is the flat ocean floor.
What effect did the continental drift have on Pangaea?
Continental drift caused Pangaea, the supercontinent, to break apart into separate landmasses over millions of years. This movement resulted in the creation of the continents we know today and influenced the formation of oceans and mountain ranges.
This layer of the crust is made of granite?
The layer of the Earth's crust that is made of granite is called the continental crust. It is less dense and thicker than the oceanic crust, primarily composed of granite and sedimentary rocks. The continental crust is found beneath the continents and is responsible for forming the landmasses we see today.
Pangea and continental drift?
Pangaea was a supercontinent that existed about 300 million years ago and eventually fragmented into the continents we know today due to the process of continental drift. Continental drift is the theory that suggests the Earth's continents move slowly over time due to the motion of tectonic plates in the Earth's crust. This movement has caused the continents to drift apart, leading to the formation of the current continental configuration.
What are the two continental masses resulting from the first rifting of Pangaea?
The two continental landmasses resulting from the first rifting of Pangaea are Laurasia in the north and Gondwana in the south. These two landmasses eventually broke apart and drifted to their current positions, forming the continents we see today.
Where is continental rifting occurring today?
Continental rifting is currently occurring in several regions around the world, most notably in the East African Rift System, which stretches from Ethiopia to Mozambique. This area is characterized by volcanic activity and the formation of rift valleys as the African continent slowly splits apart. Other examples include the Baikal Rift in Siberia and the Rio Grande Rift in the southwestern United States. These regions are marked by geological features such as earthquakes and volcanic eruptions associated with the rifting process.

What physical process created the great Rift Valley rift?
The Great Rift Valley rift was formed primarily through tectonic processes associated with the divergence of the African tectonic plate into the Somali and Nubian plates. This rifting occurs as magma rises from the Earth's mantle, causing the crust to thin and fracture. Over millions of years, these tectonic forces have led to the creation of a series of valleys and escarpments, resulting in the distinct geography of the rift. The ongoing tectonic activity continues to shape and evolve the valley today.

Is the pieces of the super-continent Pangaea began to drift apart about 255 million years ago?
Yes, the pieces of Pangaea began to drift apart about 175 million years ago, leading to the formation of separate continents as we know them today. This process, known as continental drift, was a result of plate tectonics and the movement of the Earth's lithosphere.
